Q10. What is next on the DAT roadmap?
If you consider that the DAT160 drive is DAT40 format on wider tape, then generation 7 DDS is
equivalent to DAT72 format on the wider tape. Generation 7 is expected to be released in 2009 and
will leverage the tape width enhancements made with generation 6 (DAT160 drive).
Tape length, track width, and linear bit density will increase capacity. Increased drum rotation speed
will increase performance.
The major technical challenge will be preserving “linearity” (straightness) as the head travels along

The major technical challenge will be preserving “linearity” (straightness) as the head travels along
the helical track on the wider tape. The generation 7 DDS tracks will be thinner (to give higher
capacity) and therefore will require better tracking capability from the servo system.
Summary
•
The DAT160 drive is a genuinely low-risk tape technology because so much of the design is
leveraged from previous generations and so much testing has been performed on the new parts of
leveraged from previous generations and so much testing has been performed on the new parts of
the design—mainly in the interchange area.
•
The DAT160 drive forms the stable platform for further generations of DAT technology.
•
A low media price ($40) ensures DAT160 drive technology remains the favorite tape technology
with small and medium businesses.
with small and medium businesses.
•
Backwards compatibility with an estimated 6 million installed base of DAT users has been
preserved through robust engineering.
•
A wide range of interfaces are available to protect customer interface investments both today and
tomorrow.
tomorrow.
•
The DAT160 drive has undergone extensive testing and quality assurance processes—the only
downside of which was extra development time.
